Monitor Performance

This chapter explains how to enable and view performance monitoring (PM) statistics for the Cisco ONS 15454. PM parameters are used by service providers to gather, store, set thresholds, and report performance data for early detection of problems. For more PM information, details, and definitions, refer to the Cisco ONS 15454 DWDM Reference Manual.

Step 3 If you want to change the PM interval to 15 minutes for a subtab, click the relevant subtab(s), located on the left side of the Performance tab.

Note Performance subtabs vary depending on the card.

Step 4 If you want to change the PM interval to 15 minutes for a specific port, select the port from the Ports drop-down list (where available).

Step 5 To go to any of the tabs, subtabs, or ports (found in the Ports drop-down list where available) for the card where you want to set the PM count interval, click the subtab and choose the port, if applicable from the drop-down list.

Step 6 Click the 15 min radio button.

Step 7 Click Refresh. PM parameters appear in 15-minute intervals synchronized with the time of day.

Step 8 View the Curr column to find PM counts for the current 15-minute interval.

Each monitored performance parameter has corresponding threshold values for the current time period. If the value of the counter exceeds the threshold value for a particular 15-minute interval, a threshold crossing alert (TCA) is raised. The number represents the counter value for each specific PM parameter.

Note If a complete 15-minute interval count is not possible, the value appears with a yellow background. An incomplete or incorrect count can be caused by monitoring for less than 15 minutes after the counter started, changing the node timing settings, changing the time zone settings, replacing a card, resetting a card, or changing port service states. When the problem is corrected, the subsequent 15-minute interval appears with a white background.

Step 10 Return to your originating procedure (NTP).

DLP-G132 Refresh PM Counts at One-Day Intervals

Purpose

This task changes the window view to display PM parameters in 1-day intervals.

Step 3 If you want to refresh the PM counts for a subtab, click the relevant subtab(s), located along the left side of the Performance tab.

Note Performance subtabs vary depending on the card.

Step 4 If you want to refresh the PM counts for a specific port, select the port from the Ports drop-down list (where available).

Step 5 Click the 1 day radio button.

Step 6 Click Refresh. Performance monitoring appears in 1-day intervals synchronized with the time of day.

Step 7 View the Curr column to find PM counts for the current 1-day interval.

Each monitored performance parameter has corresponding threshold values for the current time period. If the value of the counter exceeds the threshold value for a particular 1-day interval, a TCA is raised. The number represents the counter value for each specific PM parameter.

Note If a complete count over a 1-day interval is not possible, the value appears with a yellow background. An incomplete or incorrect count can be caused by monitoring for less than 24 hours after the counter started, changing node timing settings, changing the time zone settings, replacing a card, resetting a card, or changing port service states. When the problem is corrected, the subsequent 1-day interval appears with a white background.

Step 9 Return to your originating procedure (NTP).

DLP-G133 View Near-End PM Counts

Purpose

This task enables you to view near-end PM counts for the selected card and port.

Step 3 If you want to view far-end PM counts for a subtab, click the relevant subtab(s), located along the left side of the Performance tab.

Note Performance subtabs vary depending on the card.

Step 4 If you want to view far-end PM counts for a specific port, select the port from the Ports drop-down list (where available).

Step 5 Click the Far End radio button, where available. (Viewing far-end PM counts is not available on some tabs.)

Step 6 Click Refresh. All PM parameters recorded by the far-end node for the selected card on the outgoing signal appear. For PM parameter definitions, refer to the "Performance Monitoring" chapter in the Cisco ONS 15454 DWDM Reference Manual.

Step 7 View the Curr column to find PM counts for the current time interval.

Step 8 View the Prev-n columns to find PM counts for the previous time intervals.

Step 9 Return to your originating procedure (NTP).

DLP-G135 Reset Current PM Counts

Purpose

This task clears the current PM count, but it does not clear the cumulative PM count. This task allows you to see how quickly PM counts rise.

Step 1 In node view (single-shelf mode), or shelf view (multishelf mode), double-click the DWDM, TXP, or MXP card where you want to reset the current PM counts. The card view appears.

Step 2 Click the Performance tab.

Step 3 If you want to reset the PM counts for a subtab, click the relevant subtab(s), located along the left side of the Performance tab.

Note Performance subtabs vary depending on the card.

Step 4 If you want to reset the PM counts for a specific port, select the port from the Ports drop-down list (where available).

Note For all TXP and MXP cards and the GE_XP, 10GE_XP, and ADM-10G card, you cannot change the PM count interval on the Optics PM > Current Values tab.

Step 5 Click Baseline.

Note The Baseline button clears the PM counts that appear in the current time interval but does not clear the PM counts on the card. When the current time interval expires or the window view changes, the total number of PM counts on the card and in the window appears in the appropriate column. The baseline values are discarded if you change views to a different window and then return to the Performance window.

Step 6 View the current statistics columns to observe changes to PM counts for the current time interval.

Step 7 Return to your originating procedure (NTP).

DLP-G136 Clear Selected PM Counts

Purpose

This task uses the Clear button to clear specified PM counts depending on the option selected.

Caution Pressing the Clear button can mask problems if used incorrectly. This button is commonly used for testing purposes. After pressing this button, the current bin is marked invalid. Also note that the unavailable seconds (UAS) count is not cleared if you were counting UAS; therefore, this count could be unreliable when you press Clear.

Step 3 If you want to clear the selected PM counts for a subtab, click the relevant subtab(s), located along the left side of the Performance tab and click Clear.

Note Performance subtabs vary depending on the card.

Step 4 If you want to clear the selected PM counts for a specific port, select the OTN subtab or port from the Ports drop-down list (where available).

Note For all TXP and MXP cards and the GE_XP, 10GE_XP, and ADM-10G card, you cannot change the PM count interval on the Optics PM > Current Values tab.

Step 5 Click Clear.

Step 6 From the Clear Statistics dialog box, click one of the following radio buttons:

•Displayed statistics: Clearing displayed statistics erases all PM counts associated with the current combination of statistics on the selected port from the card and the window. This means that the selected time interval, direction, and signal type counts are erased from the card and the window.

•All statistics for port x: Clearing all statistics for port x erases all PM counts associated with all combinations of the statistics on the selected port from the card and the window. This means that all time intervals, directions, and signal type counts are erased from the card and the window.

•All statistics for card: Clearing all statistics for card erases all PM counts for all ports from the card and the window.

Depending on the selected auto-refresh interval, the displayed PM counts automatically update when each refresh interval completes. If the auto-refresh interval is set to None, the PM counts that appear are not updated unless you click Refresh.

Step 7 Return to your originating procedure (NTP).

DLP-G138 Refresh PM Counts for a Different Port

Purpose

This task changes the window view to display PM counts for another port on a TXP and MXP cards, GE_XP, 10GE_XP, and ADM-10G cards.

Step 1 In node view, double-click the GE_XP or 10GE_XP card where you want to view the Ethernet utilization. The card view appears.

Step 2 Click the Performance > Ether Ports > Utilization tabs.

Step 3 Click Refresh. The utilization percentages for each port on the card appear.

Step 4 View the Port # column to find the port you want to monitor.

The transmit (Tx) and receive (Rx) bandwidth utilization values for the previous time intervals appear in the Prev-n columns. For PM parameter definitions, refer to the "Performance Monitoring" chapter in the Cisco ONS 15454 DWDM Reference Manual.

Step 3 View the PM parameter names that appear in the Param column of the Current Values and History PM tabs. The PM parameter values appear in the Curr (current) and Prev-n (previous) columns. For PM parameter definitions, refer to the "Performance Monitoring" chapter in the Cisco ONS 15454 DWDM Reference Manual.

Step 3 Go to any of the tabs, subtabs, or ports (found in the Ports drop-down list where available) for the card where you want to view the payload PM parameters by clicking on the desired subtab, and choosing the port from the Port drop-down list.

Step 4 View the PM parameter names that appear in the Param column of the SONET (or SDH), Utilization, Statistics, and History tabs The PM parameter values appear in the Curr (or current), and Prev-n (previous) columns. For PM parameter definitions, refer to the "Performance Monitoring" chapter in the Cisco ONS 15454 DWDM Reference Manual.

Note The PM parameters that appear depend on the data payload and framing type provisioned on the port. Unframed data payloads such as Enterprise System Connection (ESCON), DV6000, DSI/D1 video, and high-definition television (HDTV) do not provide payload PM information. The PM parameters that appear also depend on the PPM payload configured. The TXP_MR_10E card supports three payloads; the MXP_2.5G_10G and MXP_2.5G_10E cards support the OC48/STM16 payload; the MXP_MR_2.5G and MXPP_MR_2.5G cards support the 1G FC, 2G FC, 1G FICON, 2G FICON, and 1GE payloads, and the ADM-10G supports OC-3, OC-12, and Gigabit Ethernet (GE) payloads.
